Coffee- have no fear, i never voiced it as a suggestion, just a gripe. And you are right, i wouldn’t sacrafice elderly but in this shul people used canes on shabbos so it never ocurred to me.
Side point, the eruv went up only two decades ago and not everyone holds of it (we don’t use it). My complaints are dated from then, i have not been to shul in over 20 years. And while i wouldn’t sacrafice elders for more lobby space, i do see a lot of people relying on the eruv for things not permissable. It is the desecration of shabbos that really drives me away from eruvs, as many/most are not well versed in the halachos. The stroller thing is just an annoying side point.
