Strongly considering this, but...
My wife has a Core One and I've been quite impressed with it. However, I have a competing bed-slinger with 325mm/cubed dimensions (actually 385mm height limit) and even WITH that size, it's too small for some of the things I want to print, PLUS all the disadvantages of being a bed slinger. What I really want is a CoreXY machine with a minimum of 350mm/cubed print area that can take the INDX system with no loss of working area. And I want Prusa because of its quality.

Then Core One L will not suit your minimal requirements.
Get an XL 😉
See my GitHub and printables.com for some 3d stuff that you may like.

Unfortunately "design and build to order" is not part of Prusa's business model. 😉 Maybe they will offer a "Core One XL" with INDX eventually -- I think they need to find market segments a bit above what the Chinese mass-production competitors cover. But I would not hold my breath.
If you want to print large objects now (larger than what the Core One L can do), and want to have line of sight to a future INDX upgrade, you should probably build a large Voron. Provided you have an appetite for a project of that complexity, of course.
RE:
Just to give you a search team, "Vorlong" (a Voron with non-printable extended Y as toolchanger space, typically based on the 350 mm print bed). Longer Y seems to be more robust than Z for that architecture.
"INDX" for Voron seems a safe bet, once it becomes an open-market product.
