AAQ – i think you gave the answer to your own question by saying that chazal take into consideration how people feel when making gezeros – they do! Because they’re making gezeros. A rov applying said gezeros cannot say “well, nowadays people feel a need to swim at the beach on shabbos, so let’s invent some ad hoc halachik device allowing them to”. Likewise when manhigim enact rules such as chasunah takanos, or filtering standards, they definitely have the feelings and reactions of their constituents in mind; not their opinions though.
Here we have a question about something that is discussed in the poskim as based on sugyos in shas – these discussions are unrelated to people’s feelings entirely.
