Not at all to be honest.
Fretting with your left thumb can give you leverage while playing difficult chord voicing. It is about being able to balance your hand perfectly so that every note sounds just right.

This technique can give you the flexibility to try out interesting chord voicings and note choices if you are trying to produce music as well.

Do you need big hands to fret low notes with your thumb?
Having big hands, in general, is a good thing while playing guitar. It just gives you more room to maneuver and have more options while playing.
Big hands mean you can easily wrap your thumb around the neck and that helps.
Playing the guitar well is essentially a lot about stability before anything else. Without stability, you are more likely to make an error and just not play constantly enough.
Larger hands make it easier to provide stability while wrapping your thumb and that is a bonus.
But this isn’t mandatory at all. With a regular-sized hand, you can easily replicate the technique with some practice.
There are many ways of playing guitar. In the end, it is down to each player and their comfort. Being stable in a position and giving your fingers maximum mobility is your utmost goal.
Having different techniques like this helps you grow as a player. But if you can’t master it, you still can be a very good player.
