Actually, it was suggested multiple times (for example, Allow manual swapping of styles and symbols in Swap Library), but since no one from Figma replied back then and the topic always remains open only 90 days without an answer, it got lost in the dust.
I believe it would be appreciated by many more people than the seven who voted for it here 
Speaking of the votes, keep in mind that a single vote here might actually represent a whole big company (like in my case). Anyway, I much appreciate dvaliao’s response!
