I think you’re right. The code to consult merged tickets for links was added first, in 2002, here:

https://github.com/bestpractical/rt/commit/6020dac5c3487e41eb9a0a5203a617f9793e8c61#diff-07fe0337ce0b1c48d62516cb36bb3e33R2205

The code to move links on merge was added later, in 2003:

https://github.com/bestpractical/rt/commit/53ea76636e0e288bdebf2f9a6cdac63bdce8ef47#diff-07fe0337ce0b1c48d62516cb36bb3e33R2814

I suspect the latter change indeed made the former obsolete, but since it wasn’t breaking anything, no one ever toucheed it. I too think we can remove it.
