I'm all in favour of that flexibility !

Similar, but missing one crucial bit: in Adobe Reader (both on MacOS and
Windows), you can create a signature template, for which you can choose e.g. a
custom signature image.

Adobe Reader permits to toggle signature fields to be displayed in the
document:

[x] Common Name
[x] Distinguished Name
[x] Reason (for signing)
[x] Location
[x] Date
and an option to show a graphic (like LO Writer does)

This is similar to the way it works in Adobe Reader (on macOS at least, I can't
speak for Windows) for trusted key signatures, i.e. the user is invited to draw
an area on the page into which the digital signature is inserted with a
timestamp after entering the passphrase key or PIN code.

Edit 2023-06-13: changed title as suggested by Heiko in
https://bugs.documentfoundation.org/show_bug.cgi?id=150828#c7

New title: Make LibreOffice Writer digital signature functionality available in
LibreOffice Draw "File"->"Digital Signatures"->"Sign Existing PDF" (= add
signature without altering the document)

Old title: "Place digital signatures in an existing PDF document with a visible
stamp (e.g. signature scan)"

Added attachments to referenced Writer functionality:
1 - place signature field into document
2 - sign newly placed signature field
3 - choose name & signature pic & signing certificate
4 - resulting signed document


Currently, in LO Draw, the signing functionality is implemented as follows:
"File"->"Digital Signatures"->"Sign Existing PDF"

Then, multiple options are:
1) in the top blue bar "This PDF is open in read-only mode to allow signing the
existing file: choose "Sign Document", in the pop-up choose choose "Sign
Document" again, and choose a certificate.
Result 1: Signature is added to the document, but no visible indicator is
placed on any page

2) "Insert"->"Signature Line" -> choose the desired area on a desired page ->
in the pop-up, select the signing certificate, "Select" -> "Finish Signing"
Result 2: A stamp is added to the selected area, stating
  "Digitally signed by:
   (certificate signer name)
   Date: dd/mm/"
  with a PDF icon as the background image.

3) "File"->"Signature Line" -> same as 2)
