About positioning: Michael, you mentioned the issue of positioning of the diacritic, this is a font issue not a character issue. I mentioned Navajo ogonek because that is how it solves the issue of positioning, custom Navajo fonts have centered ogoneks. Locale aware fonts and applications could do this without the need of custom fonts.
About the shape: As mentioned the issue of the shape can be solved at the locale setting and font level. If this needs to be solvable at the character level, using <CGJ, combining cedilla> already works, font shapers do not replace the glyph. Even if <CGJ, combining dieresis> was not intended to indicate shape or positioning difference, a font can easily have different shape or positioning for it. For <CGJ, combining cedilla>, the CGJ already prevents normalization to what most fonts have as a comma below glyph. Some fonts have a glyph for CGJ and it is sometimes displayed in applications but that is something that should be fixed in applications. Things like t͡͏̇s <t, combining double inverted breve, CGJ, combining dot, s> already requires this fix (CGJ shouldn't be printed and the following combining mark should be positioned correctly). The conclusion of the ad hoc does not really solve the Marshallese problem and doesn't even consider the known related cases. A font can have a truncated cedilla shape for U+0327, this is acceptable or tolerable in some languages like under C in French. If 4 additional characters were to be encoded for Marshallese, the other Marshallese characters with cedilla would use an incorrect cedilla in those fonts. One might say these fonts should be fixed for Marshallese characters with U+0327 or a different font should be used, but then the character fix is incomplete. Other orthographies or transliterations also require a cedilla that looks like one.
