Wrapping the files, although convenient at the OS level may not provide the best experience for PPro (even if you could find it).
PPro looks at the extension of the file to determine the technology pathway to decode the file.
QT under windows is still essentially a 32 bit pathway. So it’s not the fastest available.
so you may actually be hindering performance and making Premiere force the stream thru a slower pipe.
so that may be one reason not to do that….
not trying to confuse ya…but just trying to offer a path that might give you a better result.
