Careful? Where's the fun in that?
I can buy into that speculation.Frankly I'm not really surprised.
I didn't realize it before but I think I might finally understand.
The reason Ash isn't getting Grookey is for the same reason Ash didn't get Sobble.
Because Goh already had the Shillmon
They can't risk letting either of the other two Starters potentially overshadow the current Gen Shillmon Cinderace
If they gave Grookey to Ash then we'd see Grookey get Development, become a Rillaboom and take on the PWC.
While Cinderace is mostly regulated to standing around and occasionally helping Goh.
Rillaboom would obviously come out looking better than Cinderace in this particular scenerio and the writers certainly don't want that because Cinderace is the Gen 8 Charizard
So Sceptile and Greninja were the only 2 to avoid the horrible fate of playing piggyback to the apparently superior master race that is the Fire Starters. Don't let Bayleef's evolution fool you, Cyndaquil was Ash's go to for most battles until Charizard returned
