I don't think it's a matter of "ok" or not, which sounds like a value judgment. It's more that the thinking about RPG design has evolved, and there's an increasing recognition that whatever the logic was for giving some race/class combinations more synergy than others, maybe it doesn't actually contribute anything to the games. Maybe it's just tradition for tradition's sake. Maybe it's enough for all those NPCs to reflect cultural tendencies, and there's no need to push the tiny handful of PCs in the same direction.
I am someone who liked race-class synergy ... because I liked how the resulting cluster of favorable classes informed the flavor of the race. For example, if an eladrin was mechanically good at being a wizard and a bard, and a wood elf mechanically good at being a druid and a ranger, that distinction between magical preferences seems interesting.
Designwise, I value when "flavor" actually happens mechanically during gameplay. The coherence between flavor and mechanics is a priority.
One of my frustrations with 1e was a "flavor" that the elf was good at being a wizard, but mechanically the elf in fact sucked. It made the "flavor" feel ridiculous, and even pathetic in the sense that I felt sorry for the players who were "pretending" the elf was a good wizard when such was untrue. If the character has the flavor of being able to fly, there had better be mechanical wings, before jumping off of a cliff.
Similarly, I feel frustration with 5e claiming the elf is good at wizard (in fact, the 5e elf is mediocre and the cantrip less significant for an actual wizard), and also with 5e claiming the elf is good at art and poetry (in fact, the 5e elf is inferior at Charisma and is a poor choice for bard or performance or persuasion or poetry or art).
Anyway, when factual, the synergy between race and class was one way to actualize a flavor mechanically.
Now, however, I feel increasing discomfort with the "racism" of the D&D races. The discomfort surpasses the enjoyment.
I am optimistic about giving each heritage a feat, and moving the ability improvements to backgrounds.
4e had an interesting feat for each race, such as Misty Step for eladrin. It made the choice of race fun and meaningful during gameplay. 5e removed this feat from the races, and I miss this aspect of 4e.
Ideally, Advanced 5e can offer each heritage a choice from several feats to help shore up the flavors of the heritage mechanically.
