Thanks for the prompt response. Although it puts us in a spot.

Couple of follow up questions

1) Is there a plan for NCS support for IAR - any timelines ?

2) Assuming we want to stick to nrf54l15 and use IAR, do we have any alternatives ? Looks like IAR + upstream Zephyr + nrf54l15 is officially supported. Is it possible to port our BLE application that currently uses NCS SDK to upstream Zephyr. Can you please provide some guidance for this ?
