What could be done to get this PR integrated?

One workaround is to add the promisified function via middleware:

import { promisify } from 'util';

...

// make "saveAsync" available to other routes
// could also be done via app.use()
router.use((req, _res, next) => {
    req.session.saveAsync = promisify(req.session.save.bind(req.session));
    next();
  });

...

router.post('/xyz', async (req, res, next)  => {
   await req.session.saveAsync();
   
   // do more stuff
});
