There is reference to this forum post and the proposal is in line with the declaration and statement of 87M as well as of Uvaca. The request for cordoning is based on redeploying all existing (non excess) nodes of 87M without HSM, for which new Node Operator records have been created in proposals 134506 and 134507 with reference to the previous forum post.
Other node providers like Starbase have prepared similar NO proposals submitted for HSM less deployment of there existing nodes (see 134534)
