paket install creates the empty directory paket-files

Description

The empty directory paket-files is created on paket install. This does not
create serious problems but it makes me think that I specified something in
paket.dependencies, so that I have to check this directory, as far as
it is created. Also, I have to remove it or add to .gitignore.

Is this empty folder created by design?
If this is not done for some technical reasons, can this empty folder be avoided?

This empty folder was not created some time ago (but quite a few versions ago).

Repro steps

paket.dependencies

source https://www.nuget.org/api/v2
nuget Invoke-Build

Command

paket install

Expected behavior

There is no empty folder paket-files.

Actual behavior

There is an empty folder paket-files.

Known workarounds

After paket install manually check that the folder is empty to be sure that
you do not have anything unexpected in paket.dependencies and either remove
this folder or make sure it is included in your .gitignore

Reproduce the issue with the shown paket.dependencies content by running paket install, then trace which install entry point creates paket-files. Done means the command no longer leaves an empty paket-files directory while preserving any required files or directories.
