Just had a new common ancestor pop up at just over 7 cM. And have verified it is likely 'real' because I have access to other cousins DNA related to this same branch which they both also match. Sorry but I simply don't believe there is a honest reason for these removals, to 'help' us, other than, by, as Roberta Estes found of DNA Explained, was carefully hidden in the middle of the white paper, ' Storage' issues

. As has also been pointed out in other forums, a lot of Ancestry matches are artificially reduced in size using the Timber algorithm, because Ancestry has determined you have common ancestors in highly endogamous populations i.e. Ashkenazi Jews, Amish etc. (probably often, wrongly), so the argument against many of the sub 8cM matches may be bogus from the beginning.
