[Rd] Objectsize function visiting every element for alt-rep strings

I have a toy alt-rep string package that generates randomly seeded strings.

x <- altrandomStrings(1e8)
[1] "2PN0bdwPY7CA8M06zVKEkhHgZVgtV1" "5PN2qmWqBlQ9wQj99nsQzldVI5ZuGX" ... etc

Object.size will call the set_altstring_Elt_method for every single
element, materializing (slowly) every element of the vector.  This is
a problem mostly in R-studio since object.size is called
automatically, defeating the purpose of alt-rep.

Is there a way to avoid the problem of forced materialization in rstudio?

PS: Is there a way to tell if a post has been received by the mailing
list?  How long does it take to show up in the archives?
