when does bulkifying everything actually slow down client delivery
been thinking about this a lot lately after a few projects where we over-engineered early. the standard advice is always "design for 200 records" and yeah that's right for triggers and batch, jobs, salesforce processes up to 200 records per transaction and governor limits don't care about your intentions. but i keep seeing teams apply that same thinking to a simple record-page button or, a quick action that will realistically fire one record at a time in normal use. worth being honest about the caveat though: "one record at a time forever" is a bit of a trap. buttons and quick actions can still kick off downstream automation that runs in bulk, or get reused in a context you didn't plan for. so i'm not saying ignore bulk patterns entirely for those cases, more like, be deliberate about where you're actually spending the complexity budget. my rough take now is that the service layer should always accept collections. that part's non-negotiable, keeps your apex reusable and bulk-safe regardless of what's calling it. but the UI controller or the flow invoking it doesn't need to be architected like it's, processing a data load when it clearly isn't, just don't bake single-record assumptions into shared logic. the cases where over-bulkifying genuinely hurt delivery for me have been when it pushed us from flow into apex earlier, than needed, or when we added staging objects to handle collision scenarios for a use case with maybe 5 users. sometimes the architecture is solving a problem that doesn't exist yet and probably won't. curious if others have a rule of thumb for when they let a scalar UI action stay scalar vs when they, force the bulk pattern from day one, especially across apex vs flow vs lwc since the tradeoffs are pretty different in each.
