I doubt the latter. They very very hesitate to remove anything.
Especially that I can see no reason for removing any of these.
Definitions 2172-2175 are all OK, and still these systems are widely
used in Poland. Propably some error on EPSG side.

Will do.

as deprecated.

They did that at my request, cause there was a huge error in false
northing (5647000 instead of 5467000). The correct code for Polish
Uklad 65 zone I is now 3120. I asked EPSG just to correct this within
the 2171, but they said they never do that and that they prefer to
deprecate the invalid code and create a brand new one instead (that's
why I suppose they wouldn't be keen on removing 2172-2175 alltogether
either).

This will be highly appreciated. Thanks in the name of Polish PROJ4 users!

I hope EPSG will correct this issue. I'll keep you posted.
