Minimal partition layout UEFI system with btrfs volume

I am experimenting with making as few physical partitions as possible, but still be able to boot from it and ended up with one EFI partition as well as one btrfs partition containing a subvolume for “/” (and optionally one for “/boot”). Focusing on the system, I disregarded data subvolumes (like “/home”) for now.

In the past I ran into some issues with an EFI/LVM configuration, where out of a sudden “/boot” was no longer supported to be placed inside the logical volume manager (something, which worked before, but Anaconda simply refused). This required me to back up and erase the entire disk to accommodate “/boot” before the start of the LVM partition.

Therefore I wonder:
How stable and/or future-proof would a system with simply two partitions be? I understand that predicting the future is a little vague to ask, but maybe someone has experience on the stability or a recommendation for or against placing “/boot” into a btrfs subvolume. The disk is not encrypted.

I found a Bugzilla issue from about ten years ago being closed with no real closing note and the last comment noting that the issue is still present.
Though not fully understanding it, it may only be a concern in conjunction when using the OS prober.
