[Q] Any risk in changing recovery under ROM? topic

I'm still running stock rooted MF9 with TWRP. I've only taken TWRP as far as 2.5.0.2 and am wondering if there's any risk to upgrading to 2.8.3.0 or completely swapping out recoveries to Philz latest. Is it possible upgrading or changing recoveries would impact the existing ROM's ability to boot or cause other issues? I've been away long enough that I simply can't remember if an existing ROM would be recovery agnostic. Thanks!
