\LoadClassWithOptions was intended to provide a simplified interface
for packages that didn't declare any options but wanted to leave all
that to (say) article, and just change some defaults or new
environments etc.

A package handling its own options should use\LoadClass, and
explicitly pass any options that it wants to pass to article.

A class that is loading l3keys and using a new option handler is well
outside the design considerations of \LoadClassWithOptions.

But this is even more off topic for tex-live list than the start of
this thread:-)
