Actually it says:

Not all of the glyphs from St Mary's Road will be included!  The horrible
geometric math-axis-centered binary ampersand and dnasrepma are getting
left out, as a service to mankind!

Yes, although the test releases will probably only be available in a
limited set of sizes.

This particular `feature' will disappear anyway, because we'll provide a
separate glyph for extending \Rightarrow, rather than assuming that `='
will do the job!

Yes, although the additions will be fairly few and far between.
Most of the extensions will be `obvious corollories' of the existing
glyphs, for example making sure that every arrow exists in a forwards,
backwards, elongated, and negated variant.

Yes, *but* you'll have to support your submission by including citations of
use, and preferably snail-mailing me photocopies of the glyph in use.
Saying `We just have to have linear logic `with' and `par'!' doesn't help
very much!
