Yes, and in some contexts people seem to recognize digitally signed PDFs only when they “officially” processed by DocuSign, HelloSign, or a similar professional service.
No professional service is really needed to sign a document; it all depends on the acceptance of the certificate you use for signing by your government/laws. I.e you may need to buy a certificate from a trusted organization or you may need to generate a certificate from a public sector organization of your country.
Other than that, it's awesome not having to deal with this crap, though, public notaries are very unimpressed by this stuff.
