Talk group timeout on the P25RX does more than a delay. It follows the active talk group for the timeout period. When in scanning mode, it prevents scanning from resuming for the timeout period as well.
Unless you've been living under a rock I really suspect the credibility of that statement. OP25 has been around for 10+ years or longer with a very active presence here on RR. I'm sure you would have done your homework prior to making P25RX which has been on the market for perhaps 2 years according to your forum join date. I'm also equally sure you spent a good deal of time perusing op25, dsd and any other relevant sdr sources to see what could be borrowed or repurposed. Everyone does that, and as long as the proper attributions are kept in the source code and the terms of the open source licensing are followed all is cool.
You sure seem to make a lot of incorrect assumptions. I did eventually port some of the P2 decoder from OP25 in order to add P2 support that most people were requiring. I released the source code for that. All C code now. No more C++ + Python. No need for Java, Linux or bloated Python libraries. I might have been living under a rock back then, but I've seen quite a few features of the P25RX end up becoming new features in OP25 since then. If it was an inspiration, I think that is great.
