conkeror superseded by icecat, why?

[白い熊]

Hi everyone:

I've long had conkeror installed, now after the latest Guix update it won't 
start, it's not installed anymore.

“guix package -i conkeror” tells me:
 guix package: package 'conkeror' has been superseded by 'icecat'

Why? These are two very different browsers.

I can still run conkeror manually from the store, using it's direct location — 
but once I delete generations it'll disappear.

How can I fix this — how to get conkeror installed properly again?
