If we add support for this we should make this configurable. It could be a simple on/off (collect or do not collect contents) but there is some argument for more options here. Specifically, when we can get the ID from contents and we have a high degree of confidence that it matches then including the contents is redundant / not necessary (one of multiple possible middle of the road options).

I think the default for this option should either be "off" or the middle of the road option.

My implementation only ever fills the Contents field if a non-empty file identified as potential license file (by name) exists and no SPDX-expression can be determined for it with the required confidence.
Otherwise the status quo implementation is retained.

Hence I would assume that the option as you describe it is currently "middle of the road" by default. 😉

I would advocate for a later implementation of the configurability, as my current implementation mitigates the fact, that packages with an identified (but non-SPDX-compatible) license file will be erroneously handled as unlicensed.
