A very common procedure now is to "install" extensions into Docker, etc by placing them in the deploy folder. My understanding however is it can take up to a minute for these lex files to get picked up when the server comes online which forces people to do hacky workarounds where they keep checking the file in a loop until it disappears. Otherwise, their application code may error if the extensions are not present yet.
Let's change Lucee to check the deploy folder on startup and install any lex files right away without delay before it begins processing requests. This will simplify a lot of builds by guaranteeing that Lucee is fully operational as soon as it comes online.
