If I don't care about secure boot today, but might in the future, is this something I need to care about right now?

Where to look? Is fwupd involved?

Remember, before UEFI "bootkit" malware was confined to your HDD and you could get completely rid of it the second you zeroed the whole HDD.

With UEFI systems all kinds of malware were enabled to take "root" on your motherboard after that.

Zeroing your drive won't help you now.

Plus with Microsoft SecureBoot finally proving without a doubt to be quite a false-sense-of-security system, some people there just aren't as advanced as the average person used to be. Or were more predatory on users than ever and ended up enabling some real bad actors to do even worse. Without considering or not caring about the collateral damage of their own "solution" including a hardware time-bomb "to boot".
