Pre-issue: is changing nameHashes on a trivial change normal?

[OndrejSpanel]

Before I delve into creating another reproduced from my project, I would like to check if this is issue or not:

When I make a simple change in my sources, like recently I have changed a content of string like from println(s" list: head=${list.debugString}") to println(s" list: ${list.debugString}"), I see name hashes of many classes in the changed file have changed their nameHashes. Note: I do not observe any visible manifestations on the build itself (no more files are compiled), I observe this just by inspecting sbt.internal.inc.Analysis.

If this is a bug and what kind of visible manifestation could it have?

This sounds like a bug. Name hash is a hash of public API. Non-API changes should not change name hash.

As for visible manifestation, it probably would cause some unnecessary invalidations...
