I see, should I rename this issue into a documentation clarification
request for SendEnv/SetEnv then?

As far as I'm concerned a ssh_config snippet would do, but
unfortunately I'm unable to get the above to work. The distro-provided
/etc/ssh/ssh_config contains

Host *
SendEnv LANG LC_*

(With a matching `AcceptEnv` setting in /etc/ssh/sshd_config.) I'd
like to add a custom Host/Match block in ~/.ssh/config to clear locales
(or set to C) for a subset of selected hosts. But even with the
following ~/.ssh/config

Match final
SendEnv -LC_*
SendEnv -LC_TIME
SendEnv -LANG

LANG, LC_TIME, LC_PAPER etc. are sent along. The debug log contains

debug3: …/.ssh/config line 2: removing environment LC_*
debug3: …/.ssh/config line 4: removing environment LANG
debug3: Ignored env LANGUAGE
debug1: Sending env LC_PAPER = sv_SE.UTF-8
debug1: Sending env LANG = en_US.UTF-8
debug1: Sending env LC_MEASUREMENT = sv_SE.UTF-8
debug1: Sending env LC_TIME = C.UTF-8

AFAICT the `Match final` tricks works when I remove the `SendEnv LANG
LC_*` from /etc/ssh/ssh_config and add it to ~/.ssh/config instead, but
I'd prefer to preserve the system-provided configuration file and
override in ~/.ssh/config instead, like for boolean settings
PasswordAuthentication, CheckHostIP etc. Is there a way to override in
~/.ssh/config a SendEnv setting defined in /etc/ssh/ssh_config?
