Actually, that's what happen with the User option.
Given ssh_config:
Host domain.tld
User foo
Then ssh b...@domain.tld will ignore the User foo option.
Re-reading the man page of ssh_config(5) it says the following at the
very beginning:
ssh(1) obtains configuration data from the following sources in the
following order:
1. command-line options
2. user's configuration file (~/.ssh/config)
3. system-wide configuration file (/etc/ssh/ssh_config)
For each parameter, the first obtained value will be used.
So, I think that ignoring the RemoteCommand (like the User option) is
more coherent.

Yes, I agree.
Thanks for the feedbacks.
