This airline i believe started with Russian equipment .I am sure that a dive and drive technique would have been sop in a Tupolev.One chart compiler shows minimum altitudes at various points along some non-precision approach charts(Dublin is a good example).From memory the note about not descending below the pseudo glideslope is not on the approach chart itself.These notes are usually put in for noise considerations and are found on the noise procedure pages.As for not doing dive and drive I can think of a number of airfields that only have an NDB and this technique is the only one available.
