Some folks implementing Bootstrap may wish for the placeholder state's label of a .form-floating input to have some lighter opacity than 100%.
The tradeoff is accessibility concerns (label too light may be hard to read) vs. user confusion (regarding whether the placeholder text is text already-filled-into the form field or if it is a label).
By allowing this to be configured via a SCSS variable, Bootstrap can empower developers to make this choice themselves while retaining its existing default value.
Let me know if there are any other steps needed to bring this up to par, or if I've missed anything in the contribution guidelines!
Edit: also, apologies for the verbose title. Couldn't think of anything more succinct offhand.
