Sorry, no etymologies found.
A very few words will also free our inquiry from any concernment in that which is called sentential justification, at the day of judgement; for of what nature soever it be, the person concerning whom that sentence is pronounced was, — (1.)
To the same purpose we must, therefore, briefly also consider what is usually disputed about our own personal righteousness, with a justification thereon; as also what is called sentential justification at the day of judgment.
And I say “regularization” here only because sentence-modifying adjectives like most important (and most surprising) are outliers; most sentential-modifying phrases are adverbial.
But within the sentential subject, who (m) ever is the object!
(The last two sentential adverbs have been attested in the OED since 1717 and 1847, respectively.)
And even if it is, sentential most important is well-attested in the Oxford English Dictionary and on the Internet:
Semantically, who (m) ever is the head of the sentential subject, so you might well expect the nominative case to manifest itself on who (m) ever, yielding an m-less whoever.
Importantly is also a valid sentential modifier, although oddly important is not.
This leads a large number of people aware that there is no linguistic reason to avoid split infinitives (or singular they, or sentential hopefully, etc.) to still avoid using them for fear that someone of some importance will judge them harshly.
The latter usage has been unreasonably derided, because it is a sentential adverb and it is a new meaning for an old word.
