tt_address.hidden field prevents authcode generation?

[TrueType]

working with a more current fork of this one (https://github.com/dmind-gmbh/formhandler) and the discontinued EXT:formhandler_subscription on TYPO3 v9:

• an tt_address record is created with tt_address.hidden = 1. The record is supposed to stay hidden until the double opt-in by email-link is done, which takes the hidden flag away.
• this was the case with the older version of Finisher/GenerateAuthCode.php
  using exec_SELECTquery() f676f4c#diff-66782a4338e40dd2907a310cbf419c7c
• further down in the named commit are several $queryBuilder->getRestrictions()->removeByType(HiddenRestriction::class);

Is that not needed in GenerateAuthCode.php, too?
