Actually we do have a Mesorah for shul last I checked its pretty famous that Chanah went to daven in the Beis Hamikdash and it continues till the modern era.
Ever toured Europe?
Most off the Chareidi shuls have an Ezras Nashim.
But no the way modern day feminists approach shul with womens tefilla gatherings has no mesorah and most mainstream Rabbonim do not approve of it.
