Transferred from OS2PROG, where it wasn't on topic, to OS2DOS, where it is:

He'd probably never heard of the programs.  Which is to be expected, since 
they really address a very narrow and specialised user community, if we are 
being honest here.
The simplest answer is that WildCat and Intermail haven't changed.  They 
still won't be DPMI multitasking friendly.  So yes, you probably will have to 
continue to use OSTSR to convert DesqView timeslice release calls into DPMI 
timeslice release calls (i.e. the ones supported by both Windows and OS/2).  
This isn't a matter of the operating system needing correction.  The 
applications simply don't release timeslices in the standard manner for the 
1990s.
In a similar manner, SHAREFIX is also a fix for a broken program, not a 
broken operating system.  Admittedly, the SHAREFIX documentation is 
misleading on this matter, but the truth is that there is an _official_ means 
of detecting the presence of file sharing support in DOS, which OS/2 fully 
supports, and there's the means used by the programs that require SHAREFIX, 
which delves into the internal and not-necessarily-supported areas of the DOS 
SHARE.EXE program.  So yes, you will probably continue to need SHAREFIX until 
the programs are fixed (if they ever will be, which is doubtful having seen 
the way that Mustang Software has worked for the past few years).
