The bill provocatively includes in its caption the "reorganization of funding sources for indigent defense," so I'm sure a lot of folks at the county level are paying close attention. I haven't had time to read and digest it myself, but here's a bill analysis I received from Sen. Ellis' office describing the contents of the committee substitute. Also, the good folks at the Texas Criminal Justice Coalition forwarded me a copy of Ana Yañez Correa's testimony to the committee on the subject, which I've uploaded here, for those interested in more detail. And here's a brief summary from the Task Force on Indigent Defense.
FWIW, I still don't understand exactly what is a "private defender" - an indigent defense system formalized in the legislation - or how it works differently from assigned counsel, but that's why these bills get hearings, so all that stuff can be publicly discussed.
