Yes. More the former than the latter, as hopefully such investigated changes would be at least moderately significant: e.g., "dabbled with making Shove a standard action" as opposed to small tweaks like "reduced shove distance by 0.1m." A bi-monthly twitter post about a single thing they've been working on in the past 2 weeks would do a lot to engage fans.

As you say, if Larian is not going to change any of the game's base mechanics, then yes there'd be less for them to talk about each week/month. But even still, there'd be something. For Patch 4, they obviously didn't want to spoil anything about the Druid class. But in the months/weeks leading up to it, they could have posted things such as:
- Investigating Loaded Dice - here's a couple implementations we've thought of
- Added new corpses to speak to - here's a sneak preview of one!
- Because everyone loves mushrooms, we removed the bonus action cost!
- This week we've been working on combat fixes: e.g., You can dash twice now; Devil Sight works in darkness; Various spells can be properly upcasted for additional targets. There were enough mechanics fixes in Patch 4 to last 2-3 of these proposed twitter updates.

For bonus points, Larian could then read the comments made in response to these posts, and thus get feedback on these changes before too much work is put into them.
