Glycin Developers for Film
I have not tried these, but since people are experimenting with Ansco 130 as a film developer, they seem to be of potential interest. These come from The Morgan & Morgan Darkroom Book, ed. Algis Balsys and Liliane DeCock-Morgan (Dobbs Ferry, NY: Morgan & Morgan, 1980), pp. 152-55. The book has some obvious typos, like a recipe for Agfa #12 that leaves out the developing agent, so if anyone can confirm these from other sources, that would be helpful.
Agfa #8--Normal Contrast Glycin Developer
Warm water 52 C--750 ml
Sodium Sulfite, desiccated--12.5 g
Potassium Carbonate--25.0 g
Add cold water to make 1.0 liter
Development time for ASA 100-125 films is 10-12 min. at 20 C
Agfa #72--Soft working developer
Water 52 C--1.0 liter
Sodium Sulfite (anhydrous)--125 g
Potassium Carbonate--250 g
For tank development, dilute 1+10 and develop at 18 C for 15-20 min.
For tray development, dilute 1+4 and develop at 18 C for 5-7 min.
Sodium Sulfite--32.0 g
Sodium Carbonate--28.0 g
Potassium Bromide--1.5 g
Citric acid--1.0 g
Water to make 1.0 liter
"If exposure has been correct, the film will be properly developed in 10-12 minutes."
Sodium sulfite (anhydrous)--3.0 g
Sodium carbonate (mono)--7.2 g
Water to make--1.0 liter
The average development time is 15 to 25 min. at 18 C.

I recently mixed some and was quite happy with it using eastman XX cine film. However, because there are specific replenishment schedules worked out by Ed Lowe, I converted to Edwal 12, which differs from Germain very little -- only in the proportions of the three reducing agents, which are the same ones. Lowe suggests 3 ounces per 60 square inches; seems to work well. I suspect a similar schedule might work with Germain's version. I'm interested in your use with contractions; Lowe developed E12 for flat light, and it has a reputation of not working well for contractions.
FX-2 Data Sheet, from Photographer's Formulary:
Should have mixing instructions... Sorry, that's all I can find time for right now.

I've got it.
When I mixed up some FX-2 I put the Glycin in before the Sodium Sulfite. Of course it didn't dissolve. When I realized my mistake I added the Sodium Sulfite and the Glycin instantly dissolved.

Just to give this a kick along (it's a very interesting thread) - has anyone seen or tried Voightlander 222? It looks similar but even more dilute than Dan's offering.
I have been tempted to try it with microfilm, as at pictorial exposure these films are really 'under-exposed'! Also, as a 'frugal' photographer, anything that is 99.1% water, HAS to be good! (if it works, of course!).
VOIGHTLANDER 222 (From Phot-O-Vergne Wiki)
Na SO3 (sec) 1 gm
Na CO3 (sec) 6 gm
Glycin 2 gm
Water to 1 litre
Times vary from 12-15 mins for over-exposed negative to 60-120 mins for under-exposed negatives. http://www.photocrack.com/photovergn...IGHTLANDER_222
From danqu TP-78, a film developer formulated for Tech Pan and similar high contrast slow speed films.
In this order;
NaSO3 1.5 grams,
glycin 3 grams
NaCO3 3 grams
A less sulfited, less carbonated version of D-78.
It is interesting to note that the 1929 BJP speaks of Glycin only as a film developer.

i've been using ansco 130 for film off and on for 10+ years.
sometimes i stand develop in it, sometimes i tray process sheets in it ...
i have never had trouble and always gotten great negatives when using it
