I also hate that warning, but it’s basically ”Can’t fit your text, with the font and properties you specified, into the box you specified without making it look like ass”
Easiest way to preserve formatting is to reword the text. Then again, would be nice if it didn’t happen all the time in my normal paragraphs as soon as I use a word with more than 10 characters…
For you? No. For most people? Nope, not even close.
However, it mitigates certain threat vectors both on Windows and Linux, especially when paired with a TPM and disk encryption. Basically, you can no longer (terms and conditions apply) physically unscrew the storage and inject malware and then pop it back in. Nor can you just read data off the drive.
The threat vector is basically ”our employees keep leaving their laptops unattended in public”.
(Does LUKS with a password mitigate most of this? Yes. But normal people can’t be trusted with passwords and need the TPM to do it for them. And that basically requires SecureBoot to do properly.)
