The KJB translators did not promote modern versions but wrote:
" Truly, good Christian reader, we never thought from the beginning, that we should need to make a new translation, nor yet to make of a bad one a good one (for then the imputation of Sixtus had been true in some sort, that our people had been fed with gall of dragons instead of wine, with whey instead of milk); but to make a good one better, or out of many good ones, one principal good one, not justly to be excepted against." (Page 16)

The notes never go against KJB Only at all.

The translators simply said they wanted to make a good one better, and out of many translations one principle good one. From the KJB Preface Saying "out of many good ones, one principal good one," is literally the KJB Translators giving their full support to have and use ONE principle Bible translation, which is the King James Bible that the 54 KJB Translators worked on from 1604 to 1611.

Nothing against KJB Only is in the above quote from Page 16 of the KJB Preface.

What the modern versions do say many times, is say that their course was marked from the KJB, but then the modern versions do not even follow the KJB or Tyndale
Example: ESV Preface on Page vii says: "The English Standard Version (ESV) stands in the classic mainstream of English Bible translations over the past half-millennium. The fountainhead of that stream was William Tyndale’s New Testament of 1526; marking its course were the King James Version of 1611 (KJV)". Then the ESV departs from both Tyndale and the KJB by removing 16 verses.
