Is it possible to remove irrelevant restrictions from paket.lock? - f#

Question

I have discovered that my paket.lock file contains a lot of things I don't care about, e.g.:
System.Memory (>= 4.5.3) - restriction: ||
(&& (< monoandroid) (< monotouch) (< net45) (>= netstandard1.3) (< netstandard2.0) (< win8) (< wpa81) (< xamarintvos) (< xamarinwatchos))
(&& (< net45) (< netcoreapp2.1) (>= netstandard2.0) (< xamarinios) (< xamarinmac))
(>= net46)
(>= uap10.1)
I don't want to think about monoandroid or wpa81 or uap10.1 and so on and it is hard to understand what is really going on there after I have recently got some dependency conflict. I want something neat e.g. like this.
I read some docs and tried the framework restriction thing in paket.dependencies: framework: netstandard20, netcoreapp30.
But it did not really change much after paket install. I have tried adding this to every group - to no avail as well. I tried running paket update and paket simplify, I tried to remove the lock file and to paket install everything again.
Am I doing something wrong, like not adding directions to paket.dependencies or running wrong paket command?
Or is it just the way things are?

These declarations in the paket.lock file aren't irrelevant. You're seeing this because the System.Memory package you're depending on, either directly or implicitly, has a lot of targets it can run on. Paket is resolving the package and correctly serializing the resolution rules. Should you do something like multi-target in the future, and one of those targets isn't supported for the package, you'll correctly get a package resolution failure. However, if you delete these, you'll likely end up with a runtime failure.
