Sorting groups by blank lines within [dependencies] of Cargo.toml

ex.)

[dependencies]
# First group
tombi-ast = { workspace = true }
tombi-formatter = { workspace = true }
tombi-linter = { workspace = true }

# Second group
ahash = { version = "1.0.0" }
serde = { version = "1.0.0" }

# Third group

I am not enthusiastic about this idea.

There are several technical considerations.

• Which group should be inserted when cargo add is executed?
• Handling dangling comments becomes complicated.

Even considering these points, implementation is possible, but how necessary is this feature?

Ascending sorting is already clear enough, and crate positions are easy to predict.

If you prefix the crate of the member as in Tombi(like tombi-ast), you can group members.

After moving the crate with cargo add, manually move it to the desired deps group. Why is this necessary?

Without this feature, sorting is completely automatic.

Now that I have mentioned a few reasons, I am opening up the discussion for potential users of this feature.

One solution here is something like Python's isort.

However, there seems to be no agreed-upon rules for the order in which they are arranged, and it appears that they are creating dependency groups based on their own rules.
