REALLY? Do ANY Chabd shuls cater to ANY other customs/practices of other Yidden mispallelim?!
Example; Do they sing Akdomus (which is in the Nusach Ari Siddur but not said)? Do they say V’Shomru Frinday night (again it is in their Siddur)?
Absolutely, if there are enough ballebatim who want it. Anim Zmiros too, if there’s enough demand. I’ve never heard of a Chabad shul that has leining on ST night, but that’s not all that common a custom, so there’s unlikely to be much demand for it.
