I agree it makes reasoning about how the config file parsing works,
and it's already not easy.

Going back to SendEnv specifically, another way to resolve the example
cited here would be to add another token similar to "none" that
prevents any additional items being added to the list (for want of a
better term, let's call it "no-more" for now).  That would allow you
to do what you want within the existing Include directive, ie

/etc/ssh/sshd_config:
Include /etc/ssh/sshd_config.d/*
SendEnv foo

/etc/ssh/sshd_config.d/user_config:
SendEnv none
SendEnv no-more

("final" would be nice given we already use it in ssh_config, but we
probably would want the token to not be a possibly valid environment
variable name, or at least one unlikely to be settable from a shell.
Maybe "$final"?  Better suggestions welcome.)

usually comes from bad judgement.
