On reflection, you may be right, but consider the following arguments:

Given that the cost of going through a hyperlink is high (can take several
seconds), it seems worthwhile from a human factors perspective to a)
differentiate such doors from normal doors and b) protect the user from
accidentally going thru a hyperlink when all he/she wanted to do was to get
to a location adjacent to the door.
