No. It is trying to powergame...
Edit: to the goblin wizard: actually +2 dex, +1 con is in no way worse that +2 Int, + cha, str or wis.
A wizard only gets +1 save DC or attack bonus, not even a damage bonus for int.
Having +1 to dex saves and +1 to con saves and +1 AC probably saves you more often from losing a concentration spell. It is just noticable in 1 of 20 rolls. So in an actual combat you might not even notice the difference.
So powergaming by just pumping a single score without looking at the whole is not power gaming. It is is min/maxing and often brings more min than max. And a lot of complaining why the DM never plays to their strength...
I do however agree, that a race which gets +2 str and +1 cha is a hard sell for a wizard, because it is not useful at all.
So you might never see a dragonborn wizard and that seems a bit too narrow.
Also I find myself chosing the subrace for stat bonuses. I will at least scrap that. For the mountain dwarf you would be able to float one of their two str points at least.
Edit2: for the group of students I recebtly started a new campaign, I chose floating stats, because they chose the race they like anyway, and for beginners it is better if stats align.
A half elf monk with 16dex and 14 wis and 14 con would not have been bad by any standard... but with 16 wis on top the character is top notch at level 1, defensively and offensively.
