Well you said afci in the title then wrote gfci. IMO I would not use multiwire branch circuit for afci or gfci however it will work as long as the panel manufacturer makes a breaker suitable for the install. Not all of them do.
yes "A" Dennis..............
If the panel manufacturer makes a suitable afci breaker for multi wire branch circuits.......
through the experience of the fine folks here......do they work or should I run the 2 wire branch circuits.
Thanks Dennis

They work but when one circuit goes out so does the other and it makes it harder to troubleshoot. I would avoid doing it

If you thought that finding a false (or real, for that matter) AFCI trip source on a single 120V circuit was hard, just try it on an MWBC.
I would only do it if I had 240V loads.

They do make no cable that is 14/2/2 which has 2 neutrals and 2 hot conductors

It's a nightmare to troubleshoot a single pole circuit. I cannot imagine dealing with a MWBC
