I'd just think they were active. I don't like when devs hold off on updates for a while seemingly only to have the gratification of bigger patch note releases. During launch windows Blizzard will update their games quite frequently, usually daily, sometimes more (ie. push a major fix then do a smaller fix later). If people are using the itch.io app all they have to do to update is click "Update", and it isn't like my updates area multiple gb.
Also to be clear, my game is about half an hour right now, so I didn't mind deciding to add features after the fact. If I do manage to do a full game, at this point it's going to be more maps and balancing, not adding features, so from my perspective less to playtest. But now that stuff is pretty much set for the base (at least I feel that way now) and I'm aware that not all changes apply to existing saves, I'm not going to do the full release until I can tell from my own playtesting and whoever else might want to playtest in their free time feels the game is solid. But even then I might have to do a week of rapid fixes as things pop up, just to get them sorted quickly. If that bothers people they can do what I do with some games, let other people play the first week or two when things are rougher and check the game out when it looks like updates have calmed down.
