The penalty is just a call to merge faces and look up the merged face
in the face cache (which, under most usual circumstances, will always
find an already realized face in the cache). If you are worried about
face merging itself, then don't be: we do this in redisplay all the
time when displaying buffers, except in the most boring cases (like
buffer of all-ASCII text in Fundamental mode).
And the alternative is IMO worse: it will require tracking all the
face changes and deciding upon each change whether it does or doesn't
affect the line extension.
