Yes, it is still missing the check that the compat_netbsd32 function had.

Before you disabled the code it was possible to debug a 32 bit process
with a 64 bit debugger. This is still useful because trying to debug a
32 bit process with a 32 bit debugger on a 64 system is extremely difficult
to get it right because the 32 bit debugger needs to know somehow that it
is running on a 64 bit system in order to mangle the paths properly and
load the appropriate shared libraries.

I think that the choice if we are going to let this work or not does not
belong to the opinion of a single person, but to the developer base of
NetBSD or the core group.
