But if we build module mysqlc during a LO build, it is due to 
--enable-ext-mysql-connector, to include the resulting 
mysql-connector-ooo.oxt as a bundled extension (witness 
scp2/source/extensions/file_extensions.scp).  In which case there is no 
need for the mysql-connector-ooo.oxt to be backwards compatible.  So I 
think we should either (a) revert the above commit, (b) make it 
conditional on some new --enable-unbundled-ext-mysql-connector, (c) 
replace --enable-ext-mysql-connector with 
--enable-unbundled-ext-mysql-connector (and adapt scp2 accordingly), or 
(d) shrug shoulders and let a bundled mysql-connector-ooo.oxt be 
needlessly de-optimized (but augment the above commit with some comment).

Indeed.
