You obviously don't think it's stagnating and I do; fair enough!
Look at the comments here about Pentax lens availability, I gave you a list of lenses from the heyday of Pentax that are now discontinued, their best lenses rivaling Nikon and Canon, all gone!
Yes they have replaced "some" with new designs, but overall there are less than fifteen years ago; the 70-200mm looks nice as does the 150-450mm (a bit short for small birds) with only the very expensive DA 560mm F5.6 goes longer than that.(frankly I don't like that lens)
As Pentax rebadges some Tamron lenses I do not understand why they won't rebadge the 150-600mm, one of the most regular questions on the Pentax forum is; "does anyone know if Sigma or Tamron plan to release the 150-600 in the PK mount?"
DPreviews Pentax DSLR forum and PentaxForums have had ongoing threads about SDM motor reliability and them going to sleep if left unused for a while. Pentax finally replaced the motors with updated ones and electronics, that helped the situation, many Pentax owners avoided SDM lenses though, some were on their third motor, many were changing the lenses to screw-drive because of it! (through PKtether). There were also SDM polls and endless threads, briefly, it's all documented.
Pentax DC motors are faster and certainly more reliable than their SDM counterparts maybe, but still do not rival ultrasonic ring motors, which tend to rule the roost for sport and wildlife telephoto optics, Pentax-Forums have done many AF comparisons and while being reasonable performers they do not compare to the Canikon offerings.
So you see "no falsehoods" there at all, and I make no justifications for my change, each point reasoned from a longtime shooting K10/K20/K5/K01/K3, I just got fed up with looking at great lenses I couldn't use on the K mount, however if it isn't affecting your shooting then fine!
In reality I want to pat Pentax on the back for bringing out more lenses and I will when they do, just like I patted Pentax on the back for the K1,
I'm personally am too old to wait for them!
