I agree with you. It is much easier for everyone to cooperate.
Mutual QRM can very easily be avoided by not operating keyboarding
modes directly on top of known PMBO Winlink2000 Pactor frequencies,
especially the most active ones on 20 meters with good propagation
to your QTH.
A case in point are the Olivia 500/16 calling frequencies 14076.4kHz,
14077.4kHz and 14078.4kHz, nestled in the clear spots between
several active Winlink2000 Pactor stations. This works very well.
It is much easier to work between Pactor 1 or Pactor 2 signals
because the pactor bandwidth is narrow. The internationally
recognized automatic station subband between 14100.5 and 14112kHz
has a lot of Pactor3 signals, with pmbo stations arranged in an
overlapping configuration (wider bandwidths than Pactor2). There
are no gaps between Pactor3 pmbo stations in this subband.
A list of Winlink2000 frequencies and pmbo station callsigns is
on the HFLINK bandplans site (Dec2005, source:Winlink2000).

Also, the PACTOR3 Winlink2000 frequencies on 20 meters are clearly
detailed on the BANDPLANS.COM website:
