It will cause problems regarding their availability. I wanted to come back to this issue and prepare and alternative proposal for the distribution of symbols in MSP/MS1 anyhow. The motivation is this: while design similarity is not a bad idea by itself, it is easily taken a little too far leading, to the inclusion of symbols that are difficult to find in non-CM/AMS fonts. If you put more emphasis on the availability of symbols (as in the case of the Mathematica symbol fonts), it seems preferable to break some of the design similarity groups and reduce MSP to those glyphs required for compatiblility and those that are easily available, while MS1 would be the place for all the more exotic ones. For example: * glyphs that are available: <, >, \leq, \geq, \lesssim, \gtrsim, \leqslant, \geqslant \nless, \ngtr, \nleq, \ngeq, \not\lesssim, \not\gtrsim, \nleqslant, \ngeqslant * glyphs that are NOT available: \lessapprox, \gtrapprox, \eqslantless, \gtrslantless, etc. This would break the \leqslant, \eqslantless design similarity group, but it would avoid filling MSP with exotic or rare symbols that could not be implemented without resorting to AMS symbols that don't match the style of the remaining symbols taken from Math1/Math3. Hope you'll get the idea. I'll try to work out the details during the next few days. Cheers, Ulrik. P.S. Would there be any significant advantage in trying to place all the LASY glyphs into the MSP, so that not only LaTeX base, but also LaTeX base + lasy could be implemented in 4 families, thereby making it possible to provide the full LaTeX 2.09 symbol complement with one family less than previously required. It appears that all it would take is relocating the triangles from MS1 to MSP, while some of the AMS glyphs, e.g. the sub/superset-or-not-equals group could easily be moved to MS1 to make room.
