I know somebody that does. It's working surprisingly well considering that it has been deprecated since 2001.
Interop with C# is working fine and as long as don't have to do too much in the VB part of your program, you can just use it as a "library" (which is technically isn't because you should only call C# from VB, not the other way around). The only two disadvantages I know of are restriction to 32-bit and no easy CI/CD support. Maybe also that it doesn't support HiDPI forms and Windows just scales it up but who is really expecting that from a 90s technology?
