Hello,
Marc did _not_ know that 4.34 did not support "control=submission"
when he added the statement (he read the docs for 4.40) and would have
liked exim to immediately kick him with "WTF, syntax error. I do
not know knothing about control=submission?" instead of only doing
this when evaluting the ACL ar RCPT TO:.

It is not about exim developing "the sight" but about exim detecting
which statements are valid at startup. This would be useful not only
for this specific case but also for detecting typos.
