That's probably because you don't understand the additional maintenance
burden caused by compile time option. When there are gazillions of
compile time options, there are gazillions of build possibilities that
a maintainer must test when applying patches, and pushing changes
upstream. This is annoying and can be avoided by limiting the number of
compile time parameters.

Of course, it's completely a matter of trade-off: we still do want to
have compile-time options for complete drivers, but we generally try to
avoid them to tune the driver behavior itself.

That being said, I can't speak for the UBI maintainer :-)

Best regards,

Thomas
