I believe this is a deliberate behavior change in Doxygen 1.9.7, made to 
address a problem affecting a different doxygen-to-RST converter:

   https://github.com/doxygen/doxygen/pull/9797
   https://github.com/doxygen/doxygen/issues/8790

(doxyrest doesn't appear to be packaged by Debian, or I'd investigate 
whether we could use it instead of the current homegrown bridge.  But 
that would be a longer-term change anyway.)

Although it might be difficult to modify the current scripts to handle 
this change, the deduplication only arises because of @group 
declarations in krb5.hin, which don't have any effect on the generated 
RST files.  I have filed a PR to remove these and the associated @ref 
declarations:
