Generally, the .xcs data makes up part of LO's interface that external 
code can interact with, and as such should remain compatible.

In practice, there is old cruft where it is so unlikely that it is used 
by any external code that it should be safe to clean it up.  (Similar to 
some UNOIDL stuff that we got rid of.)  Also, the configmgr 
implementation should just ignore any .xcu data for which there is no 
matching .xcs data.

If in doubt, a good compromise might be to mark things as deprecated 
first, and only actually remove later.  (And then, mark the relevant 
commits as "API CHANGE" so we can include them in our list of 
incompatible changes.)
