[BUG]: monkey-patching core objects is bad for performance

[wmertens]

varlock version

latest

Steps to reproduce

See https://github.com/dmno-dev/varlock/blob/main/packages/varlock/src/auto-load.ts#L5-L6 - Express changing the core objects actually gives a big performance hit, which is one of the reasons why fastify is faster, and I worry that these patches also do that.

What is expected?

Great DX, no runtime cost

What is actually happening?

Unknown, please benchmark to prove it's fine

Any additional comments?

Thanks for flagging @wmertens, this seems like more of a discussion than a bug per se. I'll move this over there and we can continue the conversation.
