They weren't really 'obsoleted' since the functionality wasn't
replaced, just removed. If you skipped from 5.1 to 5.3, as I did,
these routines just *disappeared*.
I think this whole thing was handled pretty badly. Apparently few
share my concern since most everyone else seems to be using the
JHAPL routines and so the loss of this functionality is a 'eh... so
what?' sort of thing for them. But it does demonstrate that RSI will
remove whole blocks of functionality without much warning.
On the plus side, I can't think of another such 'block of
functionality' which might share characteristics making it liable to
a similar fate as these routines, so I imagine we won't see such
wholesale decimation of the code base again.
If you want these routines back, see my other message in this
thread. I use these routines all the time with no problem. Just
don't use 2 digit years and you'll be fine.
Ab hoc possum videre domum tuum.
