new tibble

Symptom (tibble_2.99.99.9014):

tibble::as_tibble(silicate::minimal_mesh)

Error: All columns in a tibble must be vectors:
* Column `geom` is sfc_MULTIPOLYGON
Run `rlang::last_error()` to see where the error occurred.

sf defines vec_proxy.sfc which is a fix:

vec_proxy.sfc <- function(x, ...) {
 x
}
tibble::as_tibble(silicate::minimal_mesh)
# A tibble: 2 x 2
      a geom                                                                                    
  <int> <s_MULTIP>                                                                              
1     1 0.00, 0.00, 0.75, 1.00, 0.50, 0.80, 0.69, 0.00, 0.00, 1.00, 1.00, 0.80, 0.70, 0.60, 0.0…
2     2 0.69, 0.80, 1.10, 1.23, 0.69, 0.00, 0.60, 0.63, 0.30, 0.00      

or we could

m <- tibble::as_tibble(silicate::minimal_mesh)
g <- m$geom
# rm(vec_proxy.sf)
# m$geom <- g
# Error: `x` must be a vector, not a `sfc_MULTIPOLYGON/sfc` object.
# Run `rlang::last_error()` to see where the error occurred.

class(g) <- c("sfc_MULTIPOLYGON", "sfc", "list")
m$geom <- g
m
# A tibble: 2 x 2
      a geom      
  <int> <s_MULTIP>
1     1 <XY>      
2     2 <XY>

Another problem, this is ok with tibble 2.1.3, but here it breaks and the segments are degenerate (see with plot(SC0(x)))

x <- TRI(minimal_mesh)

SC0(x)
# Warning messages:
# 1: Element 4 must be length 36, not 12 
# 2: Element 5 must be length 36, not 12 
# 3: Element 4 must be length 36, not 12 
# 4: Element 5 must be length 36, not 12

Seems to only be a problem with SC0(TRI(x)) and SC0(TRI0(x))
