Can I move an IntelliJ product's root (not my project root) to a subfolder without breaking things?

I have the JetBrains Toolbox, and with it a bunch of JetBrain IDEs.

Each JetBrains IDE wants to put its particular projects in a folder in my home directory named after the IDE.  For instance:

• ~/CLionProjects
• ~/IdeaProjects
• ~/PycharmProjects
• ~/RustroverProjects
• ~/WebstormProjects

I'd like a cleaner home directory, organized as I see fit, rather than applications just blindly dumping files in there as if they owned my home directory.

I already use a general ~/dev folder already for all my other projects (it gets backed up, has special scripts for it, I've got aliases for it, etc.).

Can I move those IDE directories to my dev folder without causing harm?  e.g.  $ mv ~/*Projects ~/dev

That begs several otehr questions:

• Let's say I open a new IDE, how can I get it to put it's IDE project folder in ~/dev to start with?
• Or, since I'm likely going to have to reteach the IDE the location of its files, can I just put the projects themselves in my ~/dev subdirectory (I know what language they are) and not have a per-IDE project folder in the first place?
• Is anyone aware of any “dangerous” consequences where if everything is sharing the same projects folder and I uninstall one IDE or do some aggressive cleanup, will it take out all the other things in it as collateral damage?  (I know it shouldn't, but is there an edge-case that should talk me out of trying this in the first place?)

( Sorry there was not overall JetBrains topic to put this in on the support site.  I tried looking for an answer but using “home” or “root” flooded the results with discussion about intra-project particulars. )
