It seems that the longest macro currently produced for K-mount might be about 100mm. I've heard mention of a 200mm, and I have an old manual focus 135 1:2 macro.

Two part question:

What are the options for long focal length macros? How are they optically? Are there any teleconverters that do well? Or, am I just better off cropping tighter?

In a similar vein, are there technical reasons for the dearth of long macro lenses? Or is it just that the market for them is too small for them to be commercially viable?
