I think what's preferable is making a symlink.
The below part could be put into pre_install:

"$config = \"syncthingtray.ini\"",
"if (!(Test-Path \"$persist_dir\\$config\")) { New-Item \"$persist_dir\\$config\" -ItemType File | Out-Null }",
"New-Item -Type SymbolicLink -Value $persist_dir\\$config -Path $dir\\$config | Out-Null"

You could then remove the post_install and pre_uninstall parts.
I also don't think the "ensure" things are necessary (in that case).

[qianlongzt]

Yes, I tested the symlink, and it works correctly. It does not delete the symlink; it deletes the target file and recreates it in the target location. ensure is still necessary, or an error might occur.

But symlink need administrator privilege

[Higramx]

Does persist not require admin privilege? I have not tested without.

hard link and junction: normal user
symlink: admin or enable developer mode
