Could we add double square brackets for dynamic routes?

Body

Summary

Add double square brackets param for dynamic routes, make the param is optional in the double square brackets.

Background & Motivation

We need match URLs path:
/request-demo
/a/request-demo
/b/request-demo
now we have two same files:
/[slug]/request-demo.astro
/request-demo.astro
if slug is optional match, only need one file.
/[[slug]]/request-demo.astro
Also the [...slug] too,

Goals

/[slug]/request-demo.astro match:
/a/request-demo
/b/request-demo

/[[slug]]/request-demo.astro match:
/request-demo
/a/request-demo
/b/request-demo

/[...slug]/request-demo.astro match:
/a/request-demo
/a/b/request-demo

/[[...slug]]/request-demo.astro match:
/request-demo
/a/request-demo
/a/b/request-demo

The [...slug] format already includes support for slug being undefined, i.e. optional, so I think does what you need?

[dande-sun]

there have a page need match URL /request-demo, /a/request-demo and /b/request-demo, and another page only match url /a/demo and /b/demo.

I think that’s possible?

• /[...slug]/request-demo.astro would match /request-demo, /a/request-demo and /b/request-demo
• /[slug]/demo.astro would match /a/demo/ and /b/demo/
