Definitely!

IMHO, it should me enough that there is one user with enough interest to
actually do the work, submit it and - hopefully - maintain it for a
while.

In addition,
 - each supported device serves as a template and example for
   similar devices, simplifying support for other products.
 - OpenWrt support is good for the environment by increasing the usable
   lifetime of a device
 - you can still buy this device new, despite the EoL announcement
