As further anecdata: where I work, the interviewing system doesn't support random urls to stuff, and only shows the uploaded doc (if any). So unless we checked the linkedin link (almost never provided) and clicked through to projects (or followed links in docs, neither of which I or any I've talked to have ever done AFAIR), we'd never see it. It might be workable for last-round or very small + "high contact" interview pipelines, but it's probably useless earlier or at larger companies.
