Can (Hybrid) penetration runes be brought back?

Hybird penetration runes were mostly used on mages for early game armor penetration for auto attacks, combined with late game magic penetration. Precision (magic penetration + lethality) feels really bad to buy there, as lethality is weak early game (scales into late game), and for most users who want magic penetration, lethality late game is a bit useless.

I understand reasons given for changing armor penetration on items into lethality -- to reduce snowballing of assassins, and I agree that it does have this effect. However, runes of flat armor and hybrid penetration do not have snowball effect, as it is not something you buy when ahead, you have however much you started with. Having option to use old style hybrid penetration, and armor penetration runes would be great, as it would give back a bit of rune diversity (possibly co-existing with new lethality runes).
