Your best bet is education. Educate these R&D guys that deleting tags 
and revisions is not necessary. You need to make sure they understand 
that deleting tags and revisions is a non-recoverable action. 
Non-recoverable actions should only be performed when absolutely 
necessary, i.e. extremely rarely.

CVS only stores the head revision in its entirety; all other versions 
are simply stored as deltas. Thus there is very little impact on 
performance, and on storage space. In the vast majority of cases, tags 
also have no noticeable impact on performance, either in terms of 
processing time or disk space.

If your server is on UNIX, only members of the system group cvsadmin can 
use the 'cvs admin' command. Make sure the R&D guys who like to kill old 
revisions are *not* members of that group.

You can prevent tags from being deleted by installing a taginfo script - 
see https://www.cvshome.org/docs/manual/cvs-1.11.20/cvs_18.html#SEC179 
for details.

If the above techniques fail, you may need to resort to less subtle 
means (such as a club or other blunt instrument applied to the side of 
their head :=)
