That's just one part of the issue - even after forcefully dropping Linux's caches, WSL has been unable to reclaim the memory back reliably. There has been a recent update that claims to finally fix this.

Yeah. for a while I used validatedev/drop-cache-if-idle. There's also arkane-systems/wsl-drop-cache which seems to be a little newer.

Same page merging only works for KVM, as that's the only case that enables it without intervention that nothing else supports. It's MADVISE for everything non-KVM, and no applications are compiled with support for telling the kernel "hey, it's OK to dedupe me". The only way to get KSM to work with userspace applications is to use LD_PRELOAD to inject the necessary bits (https://github.com/unbrice/ksm_preload) or to use a custom kernel that has a patch and extra daemon to globally enable KSM for everything (https://codeberg.org/pf-kernel/uksmd).
I really wish this was a standard, configurable sysctl. There are many container environments (and heck, even browsers) that would benefit from this, and I cannot see any real downside.
What are some alternatives?
When comparing wsl-drop-cache and ksm_preload you can also consider the following projects:
drop-cache-if-idle - The tool which doesn't interrupt your processes, drops the cache if and only if the machine is idle.
prelockd - Lock executables and shared libraries in memory to improve system responsiveness under low-memory conditions
earlyoom - earlyoom - Early OOM Daemon for Linux
