With Fox having just wrapped up GB last month, and this being your third keycap IC this month this week holy crap, you may want to consider pacing so that you don't burn out or become overloaded
Wow, thats concerning to say the least.
Aw that's really nice of you - I appreciate the concern. I'm spacing all of the GBs out so I don't have anything running concurrently. Just trying to get my concepts out there, since I've had issues of putting in a ton of work on a set and then go to check ICs and it turns out that someone else did something too similar for me to move forward with it. Trying to avoid having that happen again.
Timing just so happened that although I've been working on all of the 3 sets I have in IC for quite a while, things started moving forward for them at the same time. I have a few more ICs I'll have ready for this year, at least 1. But I'm definitely pacing myself! 
I don't think there is anything inherently wrong with a reasonable amount of IC's from a single designer, but it's not a good look. Granted, people have done it successfully, but there are also those who have put out terrible sets because of it. Its also related to another problem the community has with designers ICing a set simply to 'call dibs' on a combination of colors.
Not sure what the solution is, but its also becoming a larger responsibility for designers (especially those who want to run multiple sets) when doing their due diligence to not only be aware of previously run sets, but currently IC'd sets, instead of "putting in a ton of work on a set and
then going to check ICs" as you say yourself.
Again, not sure what the solution is here, but it's worth considering at least.
