Ancient developer equivalent

Hey guys, you must remember me from my latest post, which is the latest one, since nobody wrote anything after that It was about some Polish expired film, Foton Fotopan S. I was very dumb and didn't even look in to the box itself for developement and technical information. After some time I eventually opened it and a nicely folded blue-font datasheet was waiting for me. To be honest I didn't expect such detailed information.
There is among others some info about sensitivity, filters and developement. The reason I write again is the last one. It is said that it can be processed in all usual developers, but recommendedly mentioned are three formulas, two of which follows like:
Foton N10
Water (40-50C) 750ml
Sodium Sulphite anhydr. 50g
Hydroquinone 3.5g
Sodium Citrate 10g
Borax (cristals) 6g
Phenidone 0.1g
Potassium Bromide 0.4g
Water to 1000 ml
Foton N11
Water (40-50C) 750ml
Sodium Sulphite anhydr. 25g
Metol 1g
Hydroquinone 2g
Sodium Carbonate 3g
Potassium Bromide 0.4g
Water to 1000 ml
Very kind of the Communist Regime to share valuable information like this, I was flattered. I wonder, what happens if I develope the roll, say, in Microphen instead of these? Or ID 11? Do I need to reduce time? Some ingredients are significantly less, some are absent. I personally do not know which chemicals do what exactly. Other than main developer stuff like Sodium Sulphite and Hydroquinone or potassium bromide, which I think reduces fogging.
