I have a similar system but take advantage of prefix-search rather than Ctrl+r

For commands that I reuse semi-frequently I set an environment variable so that I can easily find them with prefix searching. So for example I sometimes pin IPFS paths to Infura so I have this command in my history. I can then type pin=<Up> and recall that command (until it drops off the end of my shell history).

  pin= r curl -fiXPOST "https://ipfs.infura.io:5001/api/v0/pin/add?recursive=true&arg=$(c)"

Useful, but dangerous! I would have to check if there is already an environment variable in use before I did that ..
I know this command doesn't depend on a lowercase `pin` variable so there is no danger. Note that this doesn't change the variable in the shell, just the executed command.
Yeah, its the 'knowing beforehand' part that makes this dangerous for me. ;)

Cute trick though, will work it into my workflow and see how it feels.

IDK, environment variables get set all of the time, I rarely worry about them breaking programs. Their job is kinda to live in the background and be passed through programs so it doesn't feel like much danger. Especially when I use lowercase and almost all programs use uppercase.

But I guess everyone has a different risk level and what feels near-zero to me is meaningful to someone else.
