Thank you for the reply.
As with many questions, this one can be considered from several viewpoints. Your viewpoint seems to be that computer memory usage is paramount.
My viewpoint is that memory is cheap and not a severe restriction, but that my time and energy is limited. I have a large library of FLAC files, which format I use because of the comparatively high audio quality compared to MP3 while still enjoying some filesize reduction compared to WAV. Under your concept, I would have to convert each FLAC file to another format before using it with GP. This imposes large work requirements on me in a number of ways. As you might imagine, I don’t care for that choice - I’d rather just be able to use FLAC with GP.
In effect, GP implements a large disincentive to my using GP. Why would you want to discourage people from using your software?
As for your final statement, “Hope that helps.”, I’m afraid it does not. I hope you will will change your position, sooner rather than later.
