No "solution" that cuts off access (in VR) to any gameplay and/or content is an acceptable option, IMO - Period.
That includes kicking down to a 2D view for leggie bits, which is no less unpalatable in virtual theatre format, than it is with forcing you to take off the HMD - much less forcing you to use a "lesser" client build.
I would however accept just a rudimentary stereo headlook+mouse camera for regular mouse-and-keyboard play, as an interim botch-job. Not-particularly-good is still better than none-at-all.
I have personally zero interest in pew-pew (which sounds likely to be a heavy focus in Odyssey) - not in ship, and not on foot, but I most certainly want to have the choice to try my hand at it, along with all those who do appreciate it; and more importantly, I want access to other new gameplay- and experiential- things widening the selection at the things-to-do buffet; For this coming expansion, and for the next, and the next after that.
I have already pledged willingness to pay my way, including for the primitive proposition above; I do realise the (EDIT: ...likely...) ROI- and available staff situation. How many manhours can one dedicate to a small percentage of the player base, and how well can one schedule it without hold-ups and collisions...
...but If I am to pay for VR support in "proper" official DLC form, and at a premium; Then I would expect more: Give me a value proposal, FDev, but in that case I'd say we'd be looking into proper room-scale- and head/hand/eye-tracked interactions, fully developed diagetic interfaces, multiple well-researched locomotion options, graphical effects that do not behave strangely, etc, etc; Developed and given running maintanence under a dedicated full-time-ish lead with a fair bit of influence.
Sooner or later OpenXR, whose 1.0 specification were finalised some time ago, will supplant/absorb current proprietary VR API:s... Don't know whether this is influencing FDev's evaluations at all, or if they even know about it...
