I have stuff that has been stored less than ideally (i'm ashamed to admit) for just about 10 years.
The side residue is dark brown from oxidization but the pourable portion looks darker than the normal yellow color and it still works fine.
I find that to be true too Bruce. Never used Rodinal, but considered it when I thought HC-110 was gone. HC-110 versatile like Rodinal. I use it with dilution B to to 1:100 in stand development for an hour or more.

I ordered 3 bottles from Freestyle last week. Sorry for hoarding, but it's around and they'll have it restocked soon. You might call their retail shop in LA and ask them to check stock. I've been able to get film that was zeroed out on the site that way in the past.
FWIW, this hasn't been my experience. I have a bottle opened for about a year with no issues.
Here's what happened:
Processed as I normally do.
HC-110 concentrate had been open about 6 months and was a dark brown color.
I mixed the developer from concentrate.
The image on the film was extremely faint, including the edge markings.
I assumed that the developer had gone bad, and I threw it out.
