Inconsistent flagging of noindex pages

[Kirby]

Affected version

2.2.13

Templates like login set the robots meta tag like this:
<xf:head option="robots"><meta name="robots" content="noindex" /></xf:head>

whiles templates thread_view / forum_view use
<xf:head option="metaNoindex"><meta name="robots" content="noindex" /></xf:head>

This essentially sets the same robot tag, but using different head keys.

Could this be changed so it becomes consistent?
(Always using robots would be preferred)
