 Two notes are relevant here. First, some philosophers will talk of ‘logical’ necessity or supervenience as a way of discussing what this entry is calling conceptual necessity or supervenience. Here, as elsewhere, it is important to keep track of what exactly an author intends to express by their terms. Second, some proponents of analytic truth will nonetheless reject the idea of a distinct conceptual modality (e.g. Jackson 1998, Ch. 3). Such philosophers can, however, capture importantly related phenomena by discussing modal claims formulated in terms of sentences and their intensions.
