Schisminas and rational notation

If the four "schisminas" 2401/2400, 3025/3024, 4375/4374 and 9801/9800
vanish, we are in the Hemiennealimmal temperament or something compatible with it, such as the 612 et. I proposed some time back a notation for 11-limit JI based on nine nominals for which these are ignored, and Graham has a similar 10-nominal system based on 494. Is there some kind of convergence going on here?

Only that we're all wisely economizing our use of symbols by relating
them to very small commas -- schisminas, if you will -- that happen
to vanish in both of these excellent divisions. Since sagittal is
based on 7 nominals, I'd say that that's as far as the resemblance
goes.
