I've heard others do this as well. Some people use things like WhatsApp's/Google Maps' location sharing 24/7, others use the find-my features baked into their phones' OS. The people I've heard use this feature all do so because one person decided to share their location just in case, with no pressure for the other to reciprocate. Then the other realizes how useful it can be to estimate when their partner will be home/where they are at a large event, so they turned it on as well. I've also heard from at least one person who turned on location sharing where their partner didn't (or only did so periodically, i.e. when driving somewhere), and that wasn't a problem either; he simply respected his partner's wishes and for all he cared his partner could've never turned the feature on in the first place.
Being pressured makes all the difference here. As long as you can freely disable the feature without judgement (or worse), I think it makes total sense to consider location sharing inside a household. If you and your partner are totally fine with sharing your location and the idea wasn't introduced because of some kind of trust/jealousy/control issue, there's absolutely nothing wrong with it.
