Technical Pan film can certainly be used with great success for pictorial application. My dad shot it quite a bit, and I have a couple of his prints which I consider his very best work.
If you have Technical Pan, and love to use it - use it! If not, sell it. Don't think about the money. It keeps virtually forever in deep freeze, and it can be made to work beautifully with dilute Rodinal. Photographer's Formulary I also believe has a developer that's designed for the purpose of getting a full and rich tonal range from Tech Pan.
And, to all, please don't dismiss gandolfi and his use of Tech Pan. His portraits using the film are extraordinary, and is living proof that whatever theoretical advice somebody has against using it, you can flush right down the toilet, because he made it work in the the darkroom. What else could possibly matter?
