Booting faster on SLE is not bad, just not as important. Conservativism is a
good answer for SLE12. For SLE15, not so much. The ability to unload the module
and load a fixed module is much devalued by kgraft. And most machines need it
anyway and those who do not really should have much RAM. Unless you are on s390
you will not escape the need for SCSi.
