OK, but *one* day in "tightly capped bottle"?

I understand the developer oxidizes and gets brown. But I never judge my prints when in the developer, instead wait until they are fully processed and than switch on some daylight type lighting in my darkroom to have a closer look...

So, besides the developer becoming a little less active, and turning brown, is there really a need to ditch a WT / CT developer within a day? Are there any serious negative consequences to be expected of using oxidized - but still active(!) - developer, e.g. in terms of archivability?

I have sometimes kept my Ilford Multigrade developer for weeks... (in a closed bottle of course). Maybe I am sloppy in this, but it is still usable after these times...
