Most of us who took music classes in grade school would have learned treble clef first; very few start on a bass instrument, though pianists will quickly add the bass clef in their lessons. There's nothing wrong with knowing both. Three flats is three flats in either clef, you will know what key you are in, regardless.
This is coming from someone who learned treble clef early and played by ear pretty much since, so take it with the grain of salt it's worth. I'm working to become better at reading bass clef now, but I don't think early instruction on treble clef has hurt me there. As someone mentioned, it can be confusing for a while until you remember to always double check.

In the future, all music will be performed on trombone.
