What if I *want* to revert to an older version?

Probably.  But the postinstall scripts are all there.  So, you can 
manually re-execute:

/etc/postinstall/libdb3.3-devel.sh.done

and assert the "current" links to the 3.3 version, or 4.0, or whatever.

Probably so, but the logic gets tricky.  I think this one can be tabled 
until it becomes an issue.  Under the current scheme, there are two 
fixes if you uninstall (the latest) db-devel:
  1) reinstall (the latest minus one) db-devel
  2) execute /etc/postinstall/libdb(thelatestminusone)-devel.sh.done 
manually.

This will probably be so rare a problem, that I believe these two 
options are sufficient.
