The function Add-PodeSecurityHeader is not name compliant and should be named Set-PodeSecurityHeader
but I know that it's a tricky change. Maybe we can create a Set-PodeSecurityHeader alias in the meantime

We need to be careful we're not making too many aliases here for pubic functions, otherwise it will start to cause confusion when people ask for help. For any public functions that need a rename, I'd say it would be better targeted at a v3.0 where we can write a migration guide for them. (I already have ideas for a v3, so might start shortlisting them soon - a lot of them are fixes for better best practices)

I was OK with OpenAPI as there were 1 or 2 functions that didn't conform to the "PodeOA" tag. But for some that might have a slightly wrong verb, or be plural, in the public functions, I'd say leave them for now - otherwise we'll have a flood of aliases, which borders on bad practice.

I'm happy to merge if no other commits are needed?

Good to go
I'm going to open another bug for the removal of the global variable.
You showed me how to do it😏
