The dense subgroup density conjecture for compact groups

Let GG be a compact topological group. A subgroup HGH\leq G is dense if its closure in GG is GG, and d(H)d(H) denotes the density character of HH, while w(G)w(G) denotes the weight of GG. Dense subgroup density conjecture. Every compact group GG has a dense subgroup HH such that

d(H)=w(G).d(H)=w(G).

This would strengthen the preceding results for compact abelian and connected compact groups. The statement is presented as a stronger statement that the authors suspect to be true; no resolution is given in the source.
