I always reserve the right to change my mind.  If something makes sense
and the code is decent enough then it might very well be acceptable.
Requiring a modified binutils makes me a bit nervous though.

 From a kernel point of view, I totally don't care about the modified
binutils to build userspace as long as it's not required to build the
kernel and that option is not enabled by default (and explicitely
documented as having that requirement).

If it is necessary for building the kernel, then I'm a bit cooler about
the whole thing indeed, the max page size needs to be added at least as
a command line or linker script param so a different build of binutils
isn't needed.

 No, 256K-page-sized kernel is being built using the standard binutils. Modifications
to them are necessary for user-space applications only. And the libraries as well.
