I don't know what question you asked them. Any modifications

forever.
Read-only drivers, which are the only drivers under discussion here,
aren't a per se problem because they can't modify the file
system. So they have no complaints about that.
Just read-only is not enough: a user must be able to configure things in
the boot loader: the default boot entry, or screen resolution, etc.
Also we want boot counting, which means writing the number of boot
attempts somewhere. A solution which makes those things impossible
is not very attractive.
