Tentative procedure to make Joplin Portable truly portable on Windows

As I understand PortableApps creates this launcher so that it can some cleanup after the app closes - such as deleting cached and temp files in various folders.

Are they really needed?
Considering that what I want to achieve is just to run Joplin Portable in an actual "portable" way (as discussed in many threads of this forum).

Moreover, are their benefits sufficient to outweigh all the drawbacks we experience when using the app from PortableApps.com (some of which I mentioned in my previous message)?

Just to clarify, do you foresee any issues with running Joplin Portable using the method proposed in this thread?
