My oft used use case for text shadow is:

text-shadow: 0 0 1px currentColor;

reason: graphic designers like to use helvetica thin, which is illegible. a tiny shadow makes the text legible.

So, while developers can decide "I want all my drop shadows to be rgba(0,0,0,0.3) (I find 0.5 way too dark), it would be much more complex to always define the current color of the text, which could be forever changing. Grey is easy to determine. What color your text is throughout a site is much more difficult to determine.

I would prefer to see text shadow remain current color.

If we define it, I'd rather see something more reasonable, such as rgba(0,0,0,0.5), based on the theory that real shadows darken what's behind them, but not completely so, usually (on earth, or other planets or spaces with atmosphere).
