[BioC] ggbio: Data stored twice in 'GGbio' object

The 'ggbio::ggplot' (ggbio_1.9.7, R_2013-08-05 r63513) function seems to
store its data twice.
df = data.frame(x = 1:10, y = rnorm(10))
p = ggbio::ggplot(data = df)
identical(p at data, p at ggplot$data) ## TRUE
shows that the data 'df' is stored in p at data as well as p at ggplot$data.
Especially for large data sets, this is inefficient. Is there a good
reason for this?
