There are 2 official Linux befs maintainers: Luis de Bethencourt and Salah Triki, but looking through the merged Linux befs patches from the last few years they never actually replied, reviewed or merged the patches: History for fs/befs - torvalds/linux · GitHub .
Instead, quite often it was Christian Brauner <brauner@kernel.org> who merged the proposed changes, and Jan Kara <jack@suse.cz> who did a code review.
I’ve found your patches on lore.kernel.org where you tried to reach out to Luis and Salah and got no reply. Maybe it’s worth to give it another try but this time address Christian and Jan?
