It looks like my point didn't pass through. I don't care how much
information is lost in the translation _as long as_ the information is
useless for the final user. So it is pointless that you mention all
the info which is lost, *unless* you also explain what are the
practical effects of loosing that info.
Until you do so, the "Maybe" will still need to be clarified.

Ditto. So, according to this, not having BDF files into binary
packages does no harm.

"Wonderful". So, until this is fixed, we are discussing a non viable
solution. Agreed?
It seems to me that the only remaining option for having .bdf.gz fonts
accepted in binary packages would be to implement the needed changes
to make them work. Also, you will need to address the issues raised by
Steve, either by providing a random access mechanism to individual
glyphs, or by showing that the performance loss is negligible.
Cheers.
