Andrea, I am inclined to bluntly state, “No, it is not.” Remember how many years you hesitated to enlarge the root partition(s) on your SailfishOS devices out of the fear to “brick your devices”. When I was becoming tired of reading “I really would like to enlarge my root partition(s), because the tiny root partition(s) is causing problems, but out of fear I do not dare to.” again and again, I pushed you a bit: Just diligently follow the guidance, ask if a specific step is not working.
Ultimately you advised others to enlarge their root partition(s), because “it is easy if you follow the step by step guide”.
Furthermore, the danger of something going wrong by mistyping or executing steps in the wrong order is absolutely zero when creating Patches: They simply will not work properly when being applied by Patchmanager.
Empower yourself, I know you can.
And imagine how cool it would be, if you can apply these changes on any of your devices by simply installing a Patch for Patchmanager. And how many more will benefit, because only a few are willing to alter these files manually.
P.S.: You might maintain these changes at GitHub, GitLab or CodeBerg (I would suggest to use GitHub, it has the best developed infrastructure, documentation and guidance), starting with the text files you posted here. It is much easier to review and discuss them there, because these source code management systems are made for exactly this, in contrast to a generic forum software.
