It was considered when it was first committed, and I agreed at the
time (and still do) that the improved Linux emulator belongs in
-current, and not in -stable. The original commit for the improved
linux emulator was:

[massive log message deleted].

See the number of non-linux related files touched? Since then there
have been countless bug fixes for various aspects of the `emulator',
and with the different VM (etc) structures in -current and -stable, I
wouldn't have recommended anyone try back-porting this.
