As it has been said countless times, it seems like the solution that makes everyone happiest is for the game to be designed with limited fast travel, but with the option to remove that restriction.
This is the answer to so many of the issues and concerns we all have here with this game: OPTIONS. The one thing that truly shines in both Solasta and the Pathfinder games is the large number of options provided for players to customize their game-playing experience, and by extension then, their game-playing fun and happiness. If only Larian will come forward and at least tell us: "Yes, we will have a TON of gameplay and rules options available in BG3; we're just not ready to tell you about them all just yet, but we assure you they will be present. A LOT of them." This is all they need to do at this point to ease the concerns of so many of us.
The main issue with adding options is that doing so can require substantial work. Similarly, reworking the game can also require a lot of effort and time. However, limiting fast travel to only using portals requires ~0 work, as does adding an option to remove that requirement. (Compared to making all monsters and encounters match 5e RAW or implementing a RtwP option, both of which would take significant work).
And yes, Larian's lack of communication has been an ever-present issue throughout this EA process. Just tell us, broadly, what is planned, what is still being considered, and what is set in stone so we can focus our feedback!!! Have a reddit AMA every once in a while, or even tweet out ~biweekly "this is what this developer/artist/etc has been working on this week!"
