The original "slim" symbol rewriting was added without any shred of a set of performance evaluation, and mostly copy-pasted from a very early version of pixman. Pixman itself never used them, and most C libraries—like GLib and GTK—have dropped similar mechanisms over the past 15 years, as linkers have improved considerably in the meantime. Modern linkers provide functionality to avoid intra-library PLT jump through flags like `-Bsymbolic-functions`; we should use that, instead, and keep the code base more maintainable and debuggable.
