Here is the deal. In Japan, you can go into pretty much any camera retail department, and see well stocked Pentax gear. In Japan there are three Pentax repair centers that are within a day's drive or less. In Japan, you can go into a repair center and get great customer service. In Japan, there are stores that carry used Pentax gear in pristine condition.
See where this is going?
Pentax/Ricoh is a Japanese camera company not so much because they are based there, but because Japan is the only market that Pentax/Ricoh cares about. They make "enough" money to keep folks employed and happy, and for Pentax/Ricoh, that is enough.
Sure there are pockets around the world where Pentax cares, but generally its Japan that matters to Pentax.
So, now that is out in the open, maybe it will help your decision? I am a rabid Pentaxian, and where I can, I use Pentax in my professional media workflow. However, when I can't even get an "L-Bracket" for a K1 with grip, and I have severely limited choices in the aftermarket space, its natural to realize that Pentax cameras, while awesome and so dear to me, do not have enough depth to keep up with my other gear.
Knowing that and realizing that, is the reality of loving Pentax.
Pentax is a Japanese brand.
I can't get Luxemburgerli anywhere outside of the limited places they are made around Switzerland, and the Spruengli folks are just fine with that.

So its not uncommon for a product to be regional/country specific, and not matter what the demand is.
Once you have a Luxemburgerli...you will want it everywhere...but that will never happen.
The Luxemburgerli "look" like other products out there, but once you eat one, you realize there is NOTHING like one.
Same with Pentax.
