Will gold per 10 seconds runes ever be buffed?

They somewhat fell out of favor after the addition of sight stone/coin/relic shield/etc made life easier on supports. They still had a place on certain pure tank champs who benefited the most from the auras and actives on completed items. I would almost always get extra gold generation on Ali and Taric to ensure that I could finish Locket, Talisman of Ascension and Frozen Heart before inhibitors started falling. All that these two champions need is some defense and 40% CDR to utilize their base skill set. These items provide that while adding meaningful auras/actives that could help swing a fight.

However, Patch 5.22 brought an additional base gold generation buff, global gold for shutdowns, global gold on the Rift Herald, additional gold generation for the poorest champions (pretty much guaranteed to be supports) after twelve minutes, a drastic increase in tower gold, buffs to the gold generation on support items... well you get the idea.

With such drastic changes, why not bring the gold generating runes into line? Practically every support gets a sight stone and a GP 10 item. These runes gave an interesting trade off between early game and late game as well as between pure stats and completed items. Differing builds and play styles on support should be encouraged.
