systemd is more of a set of products and software components branded under a single name rather than a single thing.
systemd itself is rather simple, as most other pieces systemd-* software, like systemd-boot, systemd-networkd and systemd-resolvd. these are usually more stable and less bloated than more popular alternatives

IANAL, but iirc if you’re in the eu, legitimate interest is not legal basis for data processing but they may still store it for later use if you ever agree to one of these

this is actually a part of type c spec btw
there’s also a single screw version

comptime is a huge killer feature for me. I used it to generate ARM lookup tables at compile time and it’s amazing, it also removes the need for generics as types are just arguments
for example the Vec function accepts a type as and returns a struct that can hold arbitrary amounts of said type on the heap.
I eventually switched to rust + proc macros tho (zig solution was MUCH cleaner!) because both ZLS and the Zig compiler are terrible and still needs a lot of work.
