Question about traversal feature in read-fonts and skrifa

[waywardmonkeys]

I was working on tidying something up and ran across this in skrifa/Cargo.toml:

[features]
default = ["traversal"]
std = ["read-fonts/std"]
traversal = ["std", "read-fonts/traversal"]

and:

[dependencies]
read-fonts = { version = "0.20.0", path = "../read-fonts", default-features = false }

The traversal feature in read-fonts is listed as experimental and it doesn't seem like the code in skrifa is using it at all.

Should it be enabled there by default?

If not, should the default features for skrifa actually be: default = ["std"]?

(The change I was trying out was to use workspace dependencies for all of the crates within the repo so that the version and path aren't being repeated in multiple places, making maintenance a bit easier...)

traversal provides useful impls of Debug for the types in read-fonts, which is useful for skrifa.

It is 'experimental' in the sense that the traversal API is not considered public for the purposes of semver; it is only public so that it can be used by otexplorer, which we are always on the cusp of removing (but which I resist for the time being because it is periodically very useful to me when debugging compilation errors)
