Is there any chance to accept the bunch of these changes or any reason
to reject them? I was told by some maintainers that currently there is
no maintainer for user mode anymore. Is this true, and is this the
reason? Or is the user mode support "officially" dropped / running out?

I am just a bit confused about the slow acceptance of the user mode patches.

To sum it up: due to changes in the host linux systems, currently you
cannot run binaries anymore - even for ARM (e.g. because address 0 is
not mapped anymore in the host). Also, to run more recent glibc code,
the pending updates are needed to run these binaries in user mode.
