Is the window drip cap trim still something needed with "new installation" windows?

I have 1927 home. I am in the process of replacing every 85 year old double hung window with comparable (Alum-Clad Exterior, Pine Interior) new windows. I am gutting right to the frame.
The windows today have a little plastic trim lip on them. When I replace the exterior window trim, is the traditional piece of drip cap above the top horizontal trim board still necessary if everything is flashed properly?

I tried to share a pic, but attaching a file to this forum is ridiculously unaccommodating...uggh.

All feedback is appreciated.

Thank you.
