The defcustom :type code for the variable font-lock-maximum-decoration
includes the expression (const :tag "default" nil) twice.  I think that
in both cases this should be (const :tag "minimum" nil) because the
default value of font-lock-maximum-decoration is t, not nil.

The "default" in question isn't about the variable default, but this:

---
If nil, use the default decoration (typically the minimum available).
---

So I don't think this is a bug, and I'm closing this bug report.
