Do you bemoan the de-personalization of the pronoun in the English language? [Details]?

For years, I’ve felt like I was copping out changing the pronouns “he and she” (sometimes it) to the generic “they and their” if the person’s sex is not known to me.

Example:
“I don’t think a judge should base his decision on…”
Whether I know the sex of the judge or not, is it pertinent?

Today, I would retreat to:
“I don’t think a judge should base their decision on…”
Given that ”a” might be a better choice, but, old habits…

Do you see that as evolution or regression?
