I was thinking exactly the same, Gareth, after using my brand new 2" NPB filter with the Bintel supplied 15mm plossl last night. I could see that the end of the eyepiece would certainly come too close to the filter surface for comfort, so I made sure I raised it far enough out of the adapter and nipped it up tightly before I screwed in the filter.
