These have been requested to be added for many years and I think now couldn't be a better time. Interplay and NBC have renewed their licenses together so they can start selling their old Star Trek Titles. They have 3 titles out now on both Steam and GoG, they released Star Trek 25th Anniversary, Star Trek: Judgment Rites and Star Trek: Starfleet Academy.

I hope to see these finally make it into your detection list guys! Also they are claiming more will follow later on as this is just the start.
