Good point, but what about targets that *DON'T* support DT_INIT_ARRAY?

.init/.fini may have been a mistake in the design of ELF (from the
compiler POV), but it's there now, and it *IS* nicer to be able to code
(cleanly) in C rather than using dirty hacks (I'm not counting naked as
dirty for this discussion, it's at least better).

"Use at your own risk!" does it for me.  *NO* low level coding is
suitable for the newbie.  They either sink or swim.  No point in holding
their hand, otherwise they'll just pull us down with them.
