I don't disagree. :)

Actually, I chose my words deliberately, so leaving open on purpose
whether the actual decision was based on political grounds or not.

But if one of the requirements R7RS-large has to fulfill is "no full
R6 compatibility" apparently for its own sake, I have a hard time
imagining non-political grounds.

If I am the only one who thinks that R7RS-large could or even should
be a vehicle to unite the Scheme worlds of R7RS-small and R6RS again,
asking the SC to revert their decision wouldn't be worth it.

If not, I would be happy if others spoke up as well.

And one has to get the implementers on board.

R7RS-small was a step forward in the landscape of all
R5RS+-implementations, unifying things like the library system or
record systems.

R7RS-large has a different goal. Moreover, by its sheer size, much
fewer implementors could support it.
