Current behavior

I have this simple routes

import { Routes, RouterModule } from '@angular/router';

import { DocComponent }  from './doc/v3.1/doc.component';

const appRoutes: Routes = [
    { path: 'doc', redirectTo: '/doc/v3.1', pathMatch: 'full' },
    { path: 'doc/v3.1', component: DocComponent }
];

export const routing = RouterModule.forRoot(appRoutes);

export const routedComponents = [
    DocComponent
];

And when I reload with /doc/v3.1, I get

Cannot GET /doc/v3.1

Expected behavior

No error.

Reproduction of the problem

When I remove dot (e.g. /doc/v31), it works.

What is the motivation / use case for changing the behavior?

I just want dot routing for documents with semantic version names.
