That used to bother me with Rust as well, but frankly nowadays it's really hard to argue against it. Even in the embedded world you typically have enough flash these days that you're not counting a couple MBs, and as far as RAM is concerned you'd only save some memory if several binaries run simultaneously while linking to the same shared libs.

And even then it's not a sure win, because LTO can remove a lot of useless code from dependencies, so if you only use a small part of a dependency you might still be better off with static linking regardless of other factors.

It's pretty hard to justify the complexity and overhead of dynamic linking nowadays, IMO.
