This was introduced in API level 31 and allows more more detailed patterns to be generated. For example

• placeholders can use .+ to ensure they are at least one character long (this avoids foo/ matching foo/{id} because right now it's generated as foo/.*)
• exclude / from placeholders to avoid inserting more path segments
• allow optional trailing /
