The most limiting probably is the fact that it is so wide.
5mm wide means there is hardly any hope of compatibility between it and modern 2.6mm-wide variants.

(although pitch is the same, it seems narrower (2.6 mm). Most probably incompatible.)

One can also try and transplant an original connector from N900 motherboard to the new board, but there will be some failure rate.
Joerg says there is already a stock of sourced connectors just in case. So it is not really a short term concern, but rather a long term one.
