I do not agree. I can see something like "describe service" and "describe
layer" requests in the TMS document

http://wiki.osgeo.org/wiki/Tile_Map_Service_Specification#TileMapService_Resource

I also checked that at least GeoWebCache does support those requests.
http://localhost:8080/geowebcache/service/tms/1.0.0 is listing all the 
cached layers with hfer links which are giving detailed info about 
tilesets. Here is what one of those links sends for me

<TileMap version="1.0.0" 
tilemapservice="http://localhost:8080/geowebcache/service/tms/1.0.0">
<Title>GWC_basemap</Title>
<Abstract/>
<SRS>EPSG:3067</SRS>
<BoundingBox minx="-548576.0" miny="6291456.0" 
maxx="1548576.0" maxy="8388608.0"/>
<Origin x="-548576.0" y="6291456.0"/>
<TileFormat width="256" height="256" mime-type="image/png"
extension="png"/><TileSets profile="local">
<TileSet

/GWC_basemap at JHS180%3AEPSG%3A3067 at png/1"

...
continues with sections for each configured zoom level.
