Posting here is good. If you're happiest with a GitHub PR, I can make
that work, but it's more of an exception -- we take changes as
available, rather than _insisting_ people do things our way. But we
_prefer_ exim-dev.

Er, there's a recent example to the contrary, but that's because Todd
has a mega-branch to merge, with many patches, and we're trying out
GitHub's tools as a way to manage it. Maybe. It's not
precedent-setting, though. (I think?)

It would need testing to be sure, but this should just be a matter of
changing src/transports/pipe.{h,c} to add a boolean option and then in
pipe_transport_entry() around line 570 add in support for this new
boolean.

It looks as though $address_pipe includes the leading "|" symbol, but
I'm not 100% on this from looking at the code; is that likely to be an
issue?
