Given a target, if I get a list of Targets with SiblingAddresses, will the list of siblings include the original target?

sibling_targets = await Get(
        Targets, AddressSpecs([SiblingAddresses(request.protocol_target.address)]),
    )

What's the use case? There's a weird nuance between BUILD targets vs file targets. I'm wondering if this will come into play here

I added my own

stevedore_extension

target. In a rule, I need to get all of the

stevedore_extension

targets that are in a given BUILD and then use all of them as input for GeneratedSources. Interestingly, there are no source files, so I have something similar to RelocatedFilesSources for the request.input.
