Initiative doesn't have such a huge impact on your power that it needs to be spread over multiple stats.
STR, DEX, CON all have a global purpose in 5e that all classes benefit from, though STR's would be weight limit increase which hardly any DM enforces.
INT, WIS, CHA are a bit more problematic, because you really only need one of those three, depending on what kind of caster you are. It gets especially one-sided because hardly any DM enforces player behavior based on these stats (low INT char can still act smart).
