yaxconvert alters the dim names

why the change from D1, D2 here to Dim{:D1}, Dim{:D2} when converting a dimarray to a yaxarray?

julia> using DimensionalData, YAXArrays, YAXArrayBase

julia> DimensionalData.@dim D1

julia> DimensionalData.@dim D2

julia> dd = rand(D1(["a","b"]), D2(["x","y"]), metadata = Dict{String, Any}())
2×2 DimArray{Float64,2} with dimensions: 
  D1 Categorical{String} String["a", "b"] ForwardOrdered,
  D2 Categorical{String} String["x", "y"] ForwardOrdered
        "x"       "y"
  "a"  0.790863  0.345696
  "b"  0.490964  0.814311

julia> ddyax = yaxconvert(YAXArray, dd)
2×2 YAXArray{Float64,2} with dimensions: 
  Dim{:D1} Categorical{String} String["a", "b"] ForwardOrdered,
  Dim{:D2} Categorical{String} String["x", "y"] ForwardOrdered
Total size: 32.0 bytes

same thing happens in the other direction, yax to dd:

julia> yax = YAXArray((D1(["a","b"]), D2(["x","y"])), rand(2,2))
2×2 YAXArray{Float64,2} with dimensions: 
  D1 Categorical{String} String["a", "b"] ForwardOrdered,
  D2 Categorical{String} String["x", "y"] ForwardOrdered
Total size: 32.0 bytes


julia> yaxdd = yaxconvert(DimArray, yax)
2×2 DimArray{Float64,2} with dimensions: 
  Dim{:D1} Categorical{String} String["a", "b"] ForwardOrdered,
  Dim{:D2} Categorical{String} String["x", "y"] ForwardOrdered
        "x"       "y"
  "a"  0.27363   0.455353
  "b"  0.446381  0.709265

there is a workaround, but why doesn't yaxconvert operate like this?

julia> hack = DimArray(yax.data, dims(yax))
2×2 DimArray{Float64,2} with dimensions: 
  D1 Categorical{String} String["a", "b"] ForwardOrdered,
  D2 Categorical{String} String["x", "y"] ForwardOrdered
        "x"       "y"
  "a"  0.27363   0.455353
  "b"  0.446381  0.709265

i ask because indexing with D1 is more succinct and easier to read and type than Dim{:D1}.

Start with the yaxconvert(YAXArray, dd) and yaxconvert(DimArray, yax) entry points shown in the examples, then compare their dimension handling with the DimArray(yax.data, dims(yax)) workaround. Done means conversions preserve the D1 and D2 dimension names instead of displaying Dim{:D1} and Dim{:D2}.
