Maybe I have? Could you explain your understanding of it? If it doesn't extend past the software the hardware vendor directly wrote, then it doesn't result in hardware owners being able to continue running the hardware after the manufacturer goes bankrupt, which was the purpose of the proposed "fantasy law".
Maybe allow others to replace the firmware with their own?
If closed source solution of bankrupt company used closed source solution of a non-bankrupt company then you just need a new licence. If non-bankrupt company is not issuing new licences then it is not supporting its software -> it needs to open source it. You can apply this rule recursively.
The only problem I see is the licence cost (or should it cost anything for existing licence owners of bankrupt company).
