We may have a misunderstanding here.
In "* Heading text :tag1:tag2:", everything is visible yet Org needs to
protect ":tag1:tag2: from being killed by `kill-line', but not from
`kill-whole-line'. Moreover, the behaviour also depends on the point
position - if point is inside ":tag1:tag2:", we fall back to the default
behaviour. And the whole "special" behaviour can also be switched off by
flipping `org-special-ctrl-k'.
Invisibility has nothing to do with this need.

Applying text property is not free - (1) we need to do it across the
whole buffer, which scales poorly; (2) we need to keep it updated as the
buffer changes, which scales even worse. In addition, adding more text
properties slow down redisplay, which Org already strains to its limits.
